Prien SEAL.

Application filed September 3, 1926. Serial No. 133,454.

The objects of my invention are to provide a, seal of this character which may be locked in place, which cannot be readily broken open,

vand which will be so designed as to prevent the supply pipe from beingr uns/crewed from the tzinlr er at any connection point.

I' am, of course, aware that it has been proposed to provide locking or sealing devices of various character ony strainer tubes or the like, but all of these, are so designed that either the locking device itself, ork the device including the filler pipe, may be readily removed with a suitable wrench without unlocking or breaking the seal. It is therefore the primary object, of, my invention to provide device of simple character which may be. freely turned with a wrench, or by hand, but which will prevent access to the tank unless unlocked.

With these objectsk in view my invention, in its'preferred forni, includes the novel elements and combinations of elements described lbelow and illustrated in the accompanying drawing which Figs, 1 and 2 are vertical axialI sections of my device taken at right anglesv to each other.

Fig. 1 is a section of Fig. 2 on the line 1,-1;

Fig. 2 is a section of Fig. 1 on the line 2-2;

ig. 3 is a detail of a novel flange, and :di the divided covers which may be locked over the Supply pine;

Fig. 4L is a top view of a novel element of my devie and;

Fig. 5 isA a fragmentary view of a modified form of my invention.

Reife/Ming to the drawings, 1 represents the llingpipe which `is ordinarily threaded at its lower end as shown at, 2, and adapted. to be screwed; intol aitank or reservoir, usually located under the ground. The top of pipe, 1, is closed by the screw cap, 3, having a bot-tom Hanse, 4f, preferably extending entirely around the cap. Surrounding the pipe, 1, is the outer pipe, 5, which fits loosely about pipe, 1, and'is prevented from dropping down toward the 'tank 4means of the collar, 6, secured to the pipe, 1, by set screws, 7. It is to be understood that the pipe, 5, extends down into ,the ground seine distance and that the i i collar, '6, is notea'sily accessible. The pipe, 5,

may even extend to and rest upon the tanlr, oi it may be supported by the earth. In any event the pipe, 5, extends a substantial dis=I tance into the ground so that access cannot be had to 'pipe 1. The tcp of the pipe, l5, is preiei'ahly threaded, Shown at. S, to receive the open flange, 9, which is internally` being a triiie larger than thedistanceA loe@v tween adjacent cuts in pipe, 5. rlhe flange, '9. is screwed down on pipe, 5, and locked. in place by driving the tongues, 13 ofl pipe, 5. into the notches, 12. i A u" 1 The screw cap, 3, is concealedand protected ny the divided covers, 1,4, provided' on thhir bottom edges with flange, 15, extending onlyY partially around the covers, 1,4.' andfadap'ted to fit within thn circumferentialreeess in iiange, 9. Each cover at the top is provided with lug, 16, and these lugs are adjacentv when the covers are the closed position.` Shown in i. nach Of these i'ugss pie: vided with. an opening, 17, adapted, to align when the covers are in the(':los'edA position, and through which a padlock, 1'8, may be snapped. i As a protection ifoI the lock, the covering, 19, is provided, Whichhas an enlarged:y rution, 20, for a small'distaiice about its bot om inner periphery', as Ishown in Fig. 1 and is provided, at a point diametric'ally op yosite this enlarged portion, with the set screw,u21 to loclr it in place, as shown in Fifi. 1.

To prevent pipe, 5,'witli it's`attached parts from being lifted out of the ground and over pipe, 1. the tongues, 22, of'pipef, are struck inwardly, as shown in `Figs. 2,y and lso that they will, if any attempt is inadeto lift pipe. 5. strike against the flange, 4, on cap, 3, and thus prevent access to the cap, 3, in this manner.

From a consideration of the foregoing, it will be apparent that cover-,19, may he readily removed hy looseningtlieset screw',f 21, and that by unlocking the 'padlocln 18 the difvided covers, v14, may he removed and 'access thus hfird to cap, 3. However, itwilll lie-eX treiiiely difiicult to separate the flange, 9, from pipe, 5. The flange,"9, is securely locked to pipe, 5, and any attempt to turn either the pipe or the tiang'e will simply nieve the pipe, 5, about the pipe, 1. Any attempt lto withpipe, troni tl ground w ll be iiu.m

pipe, 5, striking against the bottom of cap, 4.

It Will thus be apparent that I have provided in a very simple Way for preventing anyone from tampering with the feed pipe, 2.

3 It is obvious that many changes may be made in the details of construction herein described and illustrated in `lieir preferred form. For example, the outer pipe and its flange might be made integral, as shown in i" Fig. 5, and with such au internal diameter' or clearance, at any point, that it could not be drawn over cap, 3. rlhis and other modifications, which might he made without departing from my invention in its broad aspects, will be apparent to those skilled in the art.

It is therefore to be understood that while I have described my invention somewhat in detail for the purpose of clearness, the Words Which I have used are Words of description rather than words of limitation, and changes within the purview of the appended claims may be made Without departing from the true scope and spirit of my invention.
